plumb in LiveUpdate (WIP)
Each command that first checks preferred content (and/or required
content) and then does something that can change the sizes of
repositories needs to call prepareLiveUpdate, and plumb it through the
preferred content check and the location log update.

So far, only Command.Drop is done. Many other commands that don't need
to do this have been updated to keep working.

There may be some calls to NoLiveUpdate in places where that should be
done. All will need to be double checked.

Not currently in a compilable state.

--explain for preferred/required content matching
And annex.largefiles and annex.addunlocked.

Also git-annex matchexpression --explain explains why its input
expression matches or fails to match.

When there is no limit, avoid explaining why the lack of limit
matches. This is also done when no preferred content expression is set,
although in a few cases it defaults to a non-empty matcher, which will
be explained.

split ProvidedInfo and UserProvidedInfo
The latter is for git-annex matchexpression and matching against it can
throw an exception. Splitting out the former reduces the potential for
mistakes and avoids needing to worry about matching against that
throwing an exception.

This is more groundwork for matching largefiles while importing,
without downloading content.

make MatchFiles introspectable
matchNeedsFileContent is not used yet, but shows how to add information
about terminals. That one would be needed for
https://git-annex.branchable.com/todo/sync_fast_import/

Note the tricky bit in Annex.FileMatcher.call where it folds over the
included matcher to propagate the information.

annex.addunlocked expressions
* annex.addunlocked can be set to an expression with the same format used by
  annex.largefiles, in case you want to default to unlocking some files but
  not others.
* annex.addunlocked can be configured by git-annex config.

Added a git-annex-matching-expression man page, broken out from
tips/largefiles.

A tricky consequence of this is that git-annex add --relaxed
honors annex.addunlocked, but an expression might want to know the size
or content of an url, which it's not going to download. I decided it was
better not to fail, and just dummy up some plausible data in that case.

Performance impact should be negligible. The global config is already
loaded for annex.largefiles. The expression only has to be parsed once,
and in the simple true/false case, it should not do any additional work
matching it.

81d402216d cache the serialization of a Key
This will speed up the common case where a Key is deserialized from
disk, but is then serialized to build eg, the path to the annex object.

Previously attempted in 4536c93bb2
and reverted in 96aba8eff7.
The problems mentioned in the latter commit are addressed now:

Read/Show of KeyData is backwards-compatible with Read/Show of Key from before
this change, so Types.Distribution will keep working.

The Eq instance is fixed.

Also, Key has smart constructors, avoiding needing to remember to update
the cached serialization.

Used git-annex benchmark:
  find is 7% faster
  whereis is 3% faster
  get when all files are already present is 5% faster
Generally, the benchmarks are running 0.1 seconds faster per 2000 files,
on a ram disk in my laptop.

support standard and groupwanted in keyless mode
Only when the preferred content expression includes them will a parse
failure due to them needing keys result in the preferred content
expression not parsing in keyless mode.

matching preferred content before key is known
This will let import try to match preferred content expressions before
downloading the content and generating its key.

If an expression needs a key, it preferredContentParser with
preferredContentKeylessTokens will fail to parse it.

standard and groupwanted are not in preferredContentKeylessTokens
because they may refer to an expression that refers to a key.
That needs further work to support them.

Added mimeencoding= term to annex.largefiles expressions.
* Added mimeencoding= term to annex.largefiles expressions.
  This is probably mostly useful to match non-text files with eg
  "mimeencoding=binary"
* git-annex matchexpression: Added --mimeencoding option.

update licenses from GPL to AGPL
This does not change the overall license of the git-annex program, which
was already AGPL due to a number of sources files being AGPL already.

Legally speaking, I'm adding a new license under which these files are
now available; I already released their current contents under the GPL
license. Now they're dual licensed GPL and AGPL. However, I intend
for all my future changes to these files to only be released under the
AGPL license, and I won't be tracking the dual licensing status, so I'm
simply changing the license statement to say it's AGPL.

(In some cases, others wrote parts of the code of a file and released it
under the GPL; but in all cases I have contributed a significant portion
of the code in each file and it's that code that is getting the AGPL
license; the GPL license of other contributors allows combining with
AGPL code.)

matchexpression: Added --largefiles option to parse an annex.largefiles expression. 2016-02-03 16:58:36 -04:00

Limit annex.largefiles parsing to the subset of preferred content expressions that make sense in its context.
So, not "standard" or "lackingcopies", etc.
